Hi There!
My name is Chris and I'm from the Chicago area. I've had an interest in traffic lights ever since I was a kid and stuck my ear against and old signal controller box and wondered what was going on inside there.
I also have an interest in anything that can be tinkered with whether it's a car, engine, computer, old telephones, etc. I also like traveling, photography, and history.
I have a couple of old Crouse Hinds DT 4 way signals, a beat up model D 4 way, a single model M, a PCN 100 controller, a SVA 110 (with vacuum tubes), and a GS-4 controller.
I'm looking forward to learning more about the operation of the controllers.
